Field Detail
bundle
protected String bundle(Code)
The servlet context attribute under which the message resources bundle to be used for this exception is located. If not set, the default message resources for the current module is assumed.



extensionProcessed
protected boolean extensionProcessed(Code)
Have the inheritance values for this class been applied?



handler
protected String handler(Code)
The fully qualified Java class name of the exception handler class which should be instantiated to handle this exception.



inherit
protected String inherit(Code)
The type of the ExceptionConfig that this object should inherit properties from.



key
protected String key(Code)
The message resources key specifying the error message associated with this exception.



path
protected String path(Code)
The module-relative path of the resource to forward to if this exception occurs during an Action.



scope
protected String scope(Code)
The scope in which we should expose the ActionMessage for this exception handler.



type
protected String type(Code)
The fully qualified Java class name of the exception that is to be handled by this handler.





Method Detail
checkCircularInheritance
protected boolean checkCircularInheritance(ModuleConfig moduleConfig, ActionConfig actionConfig)(Code)

Traces the hierarchy of this object to check if any of the ancestors are extending this instance.


Parameters:
  moduleConfig - The ModuleConfig that this config is from.
Parameters:
  actionConfig - The ActionConfig that this config is from,if applicable. This parameter must be null if thisis a global handler. true if circular inheritance was detected.



getBundle
public String getBundle()(Code)



getExtends
public String getExtends()(Code)



getHandler
public String getHandler()(Code)



getKey
public String getKey()(Code)



getPath
public String getPath()(Code)



getScope
public String getScope()(Code)



getType
public String getType()(Code)



inheritFrom
public void inheritFrom(ExceptionConfig config) throws ClassNotFoundException, IllegalAccessException, InstantiationException, InvocationTargetException(Code)

Inherit values that have not been overridden from the provided config object. Subclasses overriding this method should verify that the given parameter is of a class that contains a property it is trying to inherit:

 if (config instanceof MyCustomConfig) {
 MyCustomConfig myConfig =
 (MyCustomConfig) config;
 if (getMyCustomProp() == null) {
 setMyCustomProp(myConfig.getMyCustomProp());
 }
 }
 

If the given config is extending another object, those extensions should be resolved before it's used as a parameter to this method.


Parameters:
  config - The object that this instance will be inheriting itsvalues from.
See Also:   ExceptionConfig.processExtends(ModuleConfig,ActionConfig)



isExtensionProcessed
public boolean isExtensionProcessed()(Code)



processExtends
public void processExtends(ModuleConfig moduleConfig, ActionConfig actionConfig) throws ClassNotFoundException, IllegalAccessException, InstantiationException, InvocationTargetException(Code)

Inherit configuration information from the ExceptionConfig that this instance is extending. This method verifies that any exception config object that it inherits from has also had its processExtends() method called.


Parameters:
  moduleConfig - The ModuleConfig that this config is from.
Parameters:
  actionConfig - The ActionConfig that this config is from,if applicable. This must be null for globalforwards.
See Also:   ExceptionConfig.inheritFrom(ExceptionConfig)



setBundle
public void setBundle(String bundle)(Code)



setExtends
public void setExtends(String inherit)(Code)



setHandler
public void setHandler(String handler)(Code)



setKey
public void setKey(String key)(Code)



setPath
public void setPath(String path)(Code)



setScope
public void setScope(String scope)(Code)



setType
public void setType(String type)(Code)



toString
public String toString()(Code)
Return a String representation of this object.
